Application filed June 10, 1913.

To all whom it may concern.

Be it known that we, BASIL ALFRED SLADE and FREDERICK WILLIAM THoMrsoN,both subjects of the King of Great Britain, re-

siding'at 27 Charles street, Berkeley Square,

London, England, and Birkrigg, Ashford, Middlesex, England,respectively, have invented new and useful Improvements in PortableTanks, Cesspools, and the like, of which the following is aspecification.

This invention relates to improvements in portable tanks, cesspools andthe like and more particularly to cesspools wherein human excreta aresubjected to the action of disinfecting, oxidizing or ozonizing fluidsor salts and rendered fitfor use as a ground fertilizer or manure.

According to this invention, the improved cesspool which comprises aportable tank arranged in communication by means of a suitable.detachable joint with the soil-pipe of a water-closet, is provided witha mechanical disintegrating appliance or agitator, and with a dischargevalve adapted to control the rate of flow of the contents of the tank.

By subjecting the excreta to salts of manganese, such as permanganate ofpotash, the urine is sterilized and the feces are oxidized and partlydisintegrated; the disintegration being completed by the mechanicaldisintegrating device. An additional advantage of using permanganate ofpotash is that the permanganate serves as an oxygen carrier with themass of excreta and affords a vitalizing and stimulating agent to plantgrowth. i

In order that the present invention may be clearly understood we havehereunto appended explanatory sheets of drawings,

wherein Figures 1 and 2 illustrate in sectional elevation and plan oneform of the improved cesspool, while Fig. 3 illustrates a modified formand Figs. 4 and 5 are details of Fig. 3. Figs. 6 and 7 illustratemodified constructions of the outlet tap or valve.

Referring to Figs. 1 and 2, the cesspool comprises a tank a mounted on asuitable carrier b and arranged normally under the soil-pipe c of awater closet.

' The tank a is provided with a cover a Specification of Letters Eatent.

which may be provided with a water seal as shown in Fig. 1, or may bemade to fit snug as shown in Fig. 3. This cover is provided with anannular opening in the center thereof which is provided with suitablepacking held in place by means of flanged members. Removably mounted inthis opening is a short length of pipe (Z, the upper end of which ismade in two parts, which are clamped about the lower end of the soilpipe 0 by screws d.

An outlet tap or valve 6 is provided at the lower end of the cesspool;such tap being formedwith a fiaredout inlet 6 covered in front with agrating 0 A metal ball f is inserted in the flaredfout mouth-piece. insuch a manner that a scraper, f attached to the ball works freely overthe grating c on the ball being moved up and down. The movement of theball isaccomplished by means of a lever f and a chain f connecting saidlever to the ball. By moving the ball up and down, an action similar tothat of a forceepump is obtained as well as a crushing action wherebythe choking up of the outlet passage is insured against.

A mechanical disintegrating appliance comprising a hinged grating orgrid 9 adapted, on being vibrated, to agitate or stir up the contents ofthe tank is also provided. The means for imparting movement to thisgrating comprises a chain g and a lever 9 but any other suitable meansmay be employed.

In order to render the tank air-tight, the cover a is attached to thebody portion a by means of a liquid seal supported in a re cess orcontinuous lip a formed around the upper end of the body portion.Suitable shields 7' adapted to slide vertically in guides 4' are alsoprovided on any projecting levers .suitable for the and is actuated bymeans of the leversj 1*. The grid is moreover provided wlth prongs Zwhich extend toward the first piece of netting and serve as scrapers.The discharge passage is further controlled by means of a well-knownvibratory springpressed cover hbut any other suitable valve may beemployed. The hinged grating or grld 9 1s, in this constructlon,connected to the operating lever g by meansof a link 9 instead of achain 9 as 1n the former construction.

Fig. 6 shows a modified construction of outlet tap or valve arranged toproject through the bottom of the tank a; the

scraper and grid being dispensed with in the incoming flush ofwater onthe cistern being operated.

It is especially advantageous to use permanganateof potash as'theoxidizing fluid on account of its relative cheapness and on account-ofthe advantage of potassium for plant growth. The permanganate of potashstill continues its chemicalaction even after the manure has beenapplied to the earth; the finely dividedmanganic particles whichsurround each small part of organic matter having a permanent catalvticaction whereby oxygen is liberated tothe detriment of putrefyingbacteria and protozoa and to the favorable development of aerobicbacteria -.so that'the organic matter is speedily incorporated in thehumus as plant food. If it is desired to increase the emanation ofoxygen from the manganates, acids, preferably sulfuric acid, may beaddedto the excreta.

It may herebe'pointed out that various kinds of manure can be. obtainedaccording to the manneri'n which the tank is operated. Forinstance, byonly slightly removing the ball from its seat, a liquid manure suitablefor greenhouse plants is obtained, while on the ball being wholly lifteda liquid contain ing the finer particles of the solids and suitable foroutdoor flowers is obtained. On

the ball being retained in its lifted position and the mechanicaldisintegrator operated, a

liquid containing thefresidue'of the excreta grosser feeding plants isobtained.

The well-known method of providing against siphonage of the water-closettrap can be applied to each tank as may be desired.
